For The Rock, staying jacked is literally what pays his bills — so on his last workout of the week, he had to dig real deep and muster up some inspiration.

“You got to finish the week strong because you start it all over again tomorrow," Johnson said in an Instagram video (via Men's Health). "So I woke up thinking, ‘Okay, what’s my inspiration?’ And I need a little bit of motivation.”

He thought about his daughters and his girlfriend — it's easy to be inspired by a woman going through a pregnancy, respect! But there was something else that helped him get the job done on leg day.

“But then I think about Black Panther kicking the shit out of Jumanji at the box office,” he said. “That’s all the motivation I need. Okay, that’s it. So Wakanda forever. Okay, I know, I said that with a little too much mustard. I’m very proud of Ryan Coogler and the cast of Black Panther. Congratulations. So proud. Wakanda forever. That’s all I need. Motivation enough.”

He finished the video with a particularly emphatic curse word.

Fair enough, Black Panther is doing amazingly well at the box office, raking in $700 million in the first two weeks. But Jumanji isn't doing too badly, either. It has hit $900 million since its release in December, according to ScreenRant, and is Sony's second highest-earning movie ever.

Still, Black Panther has more than one reason to inspire The Rock, or anyone else for that matter. Michael B. Jordan went through hell to get ripped for his role as Erik Killmonger — here's MBJ's Black Panther workout, so you can crush it too.
